Title: Improvements in or relating to armoured vehicles
IPC: F41A23/42
Filed: 1953-07-09
Abstract: 730,754. Gun mountings on armoured vehicles. EVEN, G. July 9, 1953, No. 19109/53. Class 92(1). An armoured vehicle has a rotatable turret 3, Fig. 1, on which guns 63 are mounted entirely externally thereof and a loading hole 4 with a removable armoured cover 7 is provided in the top plate of the armoured vehicle, the loading hole being offset with respect to the turret axis by a distance substantially equal to the pivoting radius of the loading ends of the guns. The arrangement is such that a gun loader on the vehicle has only his hands exposed while loading the guns. As shown in Figs 1, 3 a battery of six rocket tubes 63 are secured in grooves 64 in a thick frame 67 articulated on the turret by means of yokes 68 on pins 69 and having a U-shaped cutout portion 71 permitting elevation and lowering of the frame 67 by a hydraulic . jack 6 without interference by the turret. The turret comprises three members 13, 14, 15, Fig. 4, member 13 being rotatively mounted on the top plate of the vehicle, member 14 being articulated at 17 on member 13, and member 15 being rotatively mounted on member 14 so that a retractable periscope may be oriented in all directions without rotating the whole turret. The elevation jack 6, Figs. 1, 3, is pivotally carried on pins 75 on the lower member 13 of the turret. Rotation of the turret and hence training of the tubes 63 is ensured by a circular rack 77 driven by a pinion 78 rotated by an electric motor 79 or alternatively by manually operated mechanism 80. In an alternative construction the turret 3, Figs. 5, 7 is articulated through trunnions 45 on an annular member 46 rotatively mounted in the top plate, the guns 2 being mounted rigidly on side members of the turret so that training and elevation of the guns is effected by corresponding movements of the turret. The seat 24, Fig. 5 for the gun-firer is rotatably carried by a hydraulic jack and has an articulated back 40 which may be tilted forwards so that the upper edge 42 constitutes a rest for the gun-firer in an almost standing position. The seat 28 of the gun-loading man may be tilted about a pivot 32 either by means of a jack 31, Fig. 1, or by spring means 301, Fig. 9 (not shown), operated by a handle 43. Figs. 10, 11 show an ammunition feeding-chain housed in the lateral space provided on the side of the loading man position. This chain is constituted by two series of staggered links such links having two rings 50, 51 welded together, the adjacent links being held by cylindrical box members 53 passing through the rings 50, 51 and freely rotatable in them. Each box member 53 contains a shell. The whole assembly passes over two spindles 55, 56 each carrying two pinions 57. Spindle 56 is freely rotated while spindle 55 is connected through a free-wheel device 58 with a pedal 59 provided with a return spring 60. Operation of the pedal 59 by the loading man brings successive boxes 53 within his reach.

Abstract: 500,868. Moulding abrasive wheels &c. NORTON GRINDING WHEEL CO., Ltd. July 12, 1937, No. 19242. Convention date, July 16, 1936. [Class 87 (ii)] [Also in Group IV] Tn the formation of abrasive articles, e.g. grinding wheels, abrasive blocks or bricks, lapping wheels, regulating and honing sticks, from abrasive grain and heat-curable synthetic resin bond material, previously formed articles are cured by heat in an autoclave under a fluid, e.g. gas, pressure of one atmosphere gauge or more. The pressure may be sufficient to cause substantial swelling of the articles, e.g. not substantially less than the pressure of saturated steam at the curing temperatures, which may be those usually employed for each particular bond. Suitable abrasives include fused alumina, silicon carbide, bort, garnet, quartz, corundum, emery, and mixtures thereof, and suitable resins include phenol-aldehyde, e.g. phenol-furfural or phenol formaldehyde, and alkyd resins. The abrasive grains may be mixed directly with liquid or powdered bond, or be wet with a solvent, e.g. furfural, benzaldehyde, or an alcohol, before adding powdered bond. In an example, a phenol-formaldehyde bond is employed and the article cured at 80 lb. per sq. in. gauge pressure, the temperature being raised to 175 C. in ¢-hour and maintained for 1 hour longer.

Title: Process for the production of chlorinated hydrocarbons
IPC: C07C17/15
Filed: 1959-06-05
Abstract: Chlorinated aliphatic hydrocarbons are prepared by reacting at elevated temperature in the gaseous state, a C1-4 aliphatic hydrocarbon and/or a partially chlorinated derivative thereof, with hydrogen chloride and/or elemental chlorine and an oxygen-containing gas in the presence of a metal halide catalyst, said catalyst comprising a mixture of carrier particles impregnated with metal halides and carrier particles not so impregnated in a volumetric ratio of 1 part active catalyst particles to from 1 to 3 parts of inactive particles.  The catalyst particles preferably have a longest dimension of not more than 2 inches (preferably spherical) and are preferably used in a tubular reactor (preferably 1/4 inch to 4 inches internal diameter), each particle preferably having a total volume equal to that of a sphere having a diameter from 1/5 to 1/7 the diameter of the reactor.  Preferred reaction temperatures are 325 DEG C.-700 DEG C.  The reactor may be surrounded by a jacket containing a heat exchange medium, e.g. a molten mixture of KNO3, NaNO3 and NaNO2, the catalyst temperature being preferably maintained at 30 DEG C. to 375 DEG C. above that of the heat exchange medium.  Residence times may be 0.2 to 10 seconds. The oxygen-containing gas may be oxygen alone, air, oxygen enriched air, air and an inert gas or air, oxygen and an inert gas.  Preferably enough oxygen is used to ensure oxidation of the chlorinating medium and still provide some unreacted oxygen in the exit gas.  Non-chlorinated and partially chlorinated products may be recycled.  The substances chlorinated may belong to the paraffinic, olefinic or acetylenic series.  The metal halide catalyst is preferably derived from a metal of variable valency, e.g. Cu, Cr or Fe; other metal halides, e.g. of Na or K, may be present. In examples, CCl4, CH3Cl, CH2Cl2 and CHCl3 are prepared from methane. Specification 894,137 is referred to.  Reference has been directed by the Comptroller to Specification 853,754.

Abstract: 687,083. Production of alloys. EDRAS. Aug. 4, 1950 [Aug. 9, 1949], No. 19581/50. Class 82(i) A method of obtaining powders of alloys or pseudo-alloys comprises producing a fluid mass by melting at least one of the alloy ingredients, any unmolten ingredient being in the form of powder suspended in a molten ingredient, superheating one or more thin streams of the mass whereby at least one of the molten ingredients is vaporized, subjecting the superheated stream or streams to a fluid jet, whereby the ingredients are mixed, dispersed and cooled, and collecting the solid droplets of the alloy or pseudo-alloy formed. Fig. 2 shows apparatus for carrying out the invention comprising two containers 1 and 1a for receiving the ingredients of the alloy to be formed. Fluid masses from the containers pass down concentric tubes 3 and 3a and are subjected to superheating by heater 4 which may a high frequency heater or an oxyhydrogen or oxyacetylene burner. A jet of fluid, e.g. air, water or steam from nozzle 19, perpendicular to the streams of molten ingredients. mixes, disperses and cools the stream to a fine powder which passes into tube 20 in which jets of water from nozzles 21 and 22 prevent adherence of powder on the walls of the tube. In the apparatus shown in Fig. 3 a container 23 is fed with a fluid mass of mixed ingredients from container 26 to a constant level determined by overflow pipe 24. Container 23 is heated by heater 25. A molten stream passes through tube 29 to a superheater 31, the stream being dispersed and cooled by a fluid jet from nczzle 32 which is concentric with the molten stream, the resulting droplets passing through tube 33 to a container. The Specification refers to the production of Cu-Sn, Cu-Pb and Cu-Sn-Pb alloys. Specification 654,803 is referred to.
